How can a chinese girl take a visa to visit lebanon?

Hi, my name is Georges abou Mansour, I am lebanese, they told me at Beirut airport that my girlfriend can take it, so I book tickets, but the Chinese government didn't let her go out because there is no visa on her passport, so I delayed our flight till next Thursday, please can you tell me if she can get it from the embassy? Can take it and take the passport before next Thursday? We live n Guangzhou
